G80 Real Life Test

Ok... the G80 has been a topic of discussion forever! There were even people who refused to believe that it fully "locked" both rear tires together.

 

This is a video that I took to show how it works. You can not see it in this video (and in hindsite I wish I took a close up picture) but to get up this incline the passenger rear tire comes off the ground about 2".

 

I was also a bit surprised by the noise at first so I let off the gas... that's just the clutch packs engaging to lock the two axles together. Normally you won't hear this but since I engaged it at the minimum RPM it was a "slow" engagement.

 

Enjoy!

A couple of videos (from YouTube) that really help explain how the G80 works.....

G80 didn't do so well on this test :D

 

 

 

In this video it actually seems like they stopped the GM trucks while they progressed forwards in 2wd. I never quite understood what they were doing, but it looked like the trucks would have continued just fine had they just kept going to me.

Looked like the G80 did what it was supposed to... both tires were spinning

I agree, it does not seem like they knew the best way to operate the G80. Once it locks you have to stay on the throttle or it will unlock.

 

With that said, that test would be hard on the G80.

Agreed guys...I seen the vid with the rollers...and that's a lot slicker than using water and tiles....and the G80 was the only thing that could make it up there. The Torsen rear diff in the Fords is not a bad diff by any stretch of the imagination, but I would rather have a locker over an LSD.

 

I also did not see them, anywhere in that video, actually show the Chev/GMC trucks front wheel spinning to prove it was in 4wd...and why would you switch to 4HI when those trucks obviously have the Auto function.

Its weird to see almost every video out there praise the G80 to high heavens and these guys say it was near the end of the pack.

Hence the title of this thread... :D

 

No LSD rear is going to get up the incline i drove up in 2WD. Figured I'd post a first hand test.

No Doubt man.

traction control is for chumps...lockers are all the T/C we need.

What a dumb test result of performance by these carscom amateurs. On the GMC, the tire with traction spun? on the pavement, which was not a failure requiring 4WD. Notice that the ford climbing the first time, the pavement dry on the right side, and the left tire shifted over and looked to have caught the pavement. It was a wet tire, with little weight on the back end, driving it slower than the other trucks, and they noted that the other trucks where HEAVIER. Note they drove both rear tires of the GMC through water before making the last climb. Anyone ever watch a drag race and see what they do to warm up the tires before taking off?? Hello? The G80 locker did what it was supposed to. Why in the world did? they stop the truck part way up? That was on purpose. Dumb. I'll take a mechanical locking diff any day over some computerized system that alters the function of the engine and braking system. :dunno:

      Transmission Temperature Hitting 220s

      By newdude · Posted

      It is working as designed.  NHT and non NHT trucks have the same exact transmission cooling setup.  NHT just gets a larger radiator.     The transmission cooler loop on these is as follows.     -Transmission out goes into an oil to water heat exchanger (item #1 in the first illustration below).  This exchanger has engine coolant opposite the transmission fluid and uses engine coolant to warm and then regulate the transmission fluid temperature when its in the operating window.   - From the cooler it goes to a thermal bypass valve (item #11 in the 2nd illustration below).  If the ATF has not reached the temp to open the bypass (194F), it loops back.   - When it reaches 194F, the thermostat opens and ATF then flows out to the oil to air auxiliary cooler (item #17 in the 2nd illustration) at the front of the truck.  From there it goes back to the transmission.     Your only fix would be to swap for the PPE thermal bypass delete block which will open the loop to the aux cooler all the time.  It will STILL run warm, probably 170-200F, but that's as low as you'll get it as its still flowing through the oil to water exchanger.

      Most say the oil temperature needs to above the boiling point of water to rid it of moisture and long enough to dry it. Many think that is about a hour at 212 F or more. Those people have never line dried cloths in a Midwest winter. Leave a pan of water sitting on the counter and eventually it all evaporates. So heat drives the time it takes. Water in oil under 175 F, the Nitration initiation temperature, is a minimum then for temperature and samples I've done that use Karl Fisher method say about a hour (in a healthy well tuned motor) over 175 F will dry it to under 800 ppm. Low enough to not be much of a factor. Motors with weak rings will take longer and the colder the air temperature the longer it takes.   On a cold motor there is also the condensation temperature. Blowby gases that contain moisture are subject to that cold cylinder wall, like sweat on a glass of ice tea. But also subject to the Law of Partial Pressures. Wear studies by GM and the DOD  indicate wear is a real issue below 85 F and a concern to 140 F but doesn't become a minimal factor until about 160 F. You know this intuitively when you see water vapor exit the exhaust pipe until the system gets above the dew point. It isn't magic, it's physics and it fascinates me. I know you didn't ask but....I over share sometimes. 😉    You keep the Camaro's high and tight.

      Move further away.   Benefit of living out - none of our cars get short cycled, plenty of warm up time.   Curious how much time/temperature it takes to drive moisture/condensation out of the engine?

      Transmission Temperature Hitting 220s

      Switch a a 100% synthetic trans fluid, Amsoil works for me.

      Transmission Temperature Hitting 220s

      By DustMcGrath · Posted

      First of all sorry, I know there are a ton of transmission temperature threads...   My truck is a 2025 LZ0 High (10l89 10-speed) High Country with NHT max trailering package. The NHT package is supposed to have "enhanced cooling."   Normally the trans temp sits around 200. It seems like with any real stress it quickly jumps into the 220s (for example climbing a grade unloaded at lower speeds). I haven't towed much with this truck, but I'm concerned if it gets this hot unloaded.    I've tried a few different things to keep the temps down (tow/haul mode, sport mode, low range when that makes sense) and nothing seems to affect it.    I'm curious if others are the same behavior or if anyone has found techniques to keep the temps down. It seems like it just can't handle reduced airflow at lower speeds, even with relatively light loading.    Thanks!
